tallic strip surrounding the door opening,

and having a door which is somewhat thicker than the adjacent facing ofthe door opening and which, when closed, will press against saidflexible strip so as to form a perfectly tight joint between the insidemargin of the door and the flexible strip to shut off all circulation ofair through the joints between the door and the facing of the dooropening.

Another object of the invention is to provide a refrigerator door and apacking around the door opening so that the door, when closed, will forma perfectly tight fit and thus shut off all circulation of air throughthe door opening and which, at the same time, is of simple constructionand may be cheaply andeasily manufactured.

With the above and other objects in view the invention has particularrelation to certain novel features of construction, operation, andarrangement of parts, an example of which is given in this specificationand illustrated in the accompanying drawings, wherein Figure 1 is afragmentary transverse sectionalview of a refrigerator taken through thedoor and showing the door partially open.

Figure 2 shows a view similar to that shown in Figure 1 with the doorshown closed and,

Figure 3 is a fragmentary sectional View showing the door opening viewedfrom the inside of the refrigerator.

Inthe drawings the numeral 1 designates the refrigerator as a whole.This r'efrig erator has the door opening 2 and the door 3 hinged theretoto 0 en and close said opening. The facing o the door opening ispreferably stepped, as shown, and the mar-' gm of the door iscorrespondingly stepped so that the door will form three points of thedoor is closed.

contact with the facing all the way around, as shown. Surrounding thedoor opening on the inside there is a metallic strip 4: which is miteredat the corners and which is flexible. This strip is preferably made ofcopper, although other material may be used and it is preferably securedin place by means of the quarter rounds 5 which are nailed in the anglesas shown in the figures. The free margin of the strip 41 is preferablyslightly curved outwardly and the inner face of the door, when the dooris closed, projects inwardly slightly beyond the inner surface of thefront wall of the refrigerator and thus presses against said strip 4 allthe way around, said strip yielding slightly, as shown in Figure 2 andthus forming a very tight joint and preventing all circulation of airthrough the door opening. This construction greatly increases theefiiciency of the refrigerator and makes it more economical in the useof ice and causes it to hold alower temperature.

VVhat I claim is 1. In a refrigerator having a door opening, a flexiblemetallic strip surrounding the door opening and lying closely againstthe inner side of the refrigerator wall and projecting outwardly beyondthe facing of the door opening all the way around, and a door themargins of whose inner face press against said strip all the way aroundwhen the way around when the dooris in closed position.

3. In a refrigerator having a door opening, a flexible metallic stripentirely surrounding said opening and lying closely against the insideof the refrigerator wall and having its free margin projecting outwardlybeyond the door facing all the way around and. being outwardly curved,and a door provided to open and close said opening, and the margin ofwhose inner way around the door opening and lying closely against theinside of the refrigerator wall and having its free margin projectingoutwardly from said door facing all the way around and being outwardlycurved but substantially parallel with the inside doorv facing, a doorprovided to open and close said opening, the margin of whose inner facepresses against the outer side of said outwardly curved flexiblemetallic strip all the way around when the door is closed.

5. In a refrigerator having a door opening, an outwardly curved flexiblemetallic strip surrounding said opening, said flexible metallic stripbeing secured at one end in the corner formed by the side and frontwalls all the way around the door opening and lying closely against theinside of the refrigerator wall and having its free margin projectingslightly out into the door opening all the way around and beingsubstantially parallel with the inside door facing, a door provided toopen and close said opening, the margin of whose inner face presses 4ing provided with a surrounding facing, a

flexible metallic strip surrounding said opening forming a rectangularframe-like structure all the way around and project ing from said doorfacing, a securing means forming a frame-like structure holding saidmetallic strip; securely in the inside corner formed by the front andinside walls all the way around, a door hinged to the refrigerator andarranged to open and close said opening and whose inner face projectsinwardly beyond the inner face of the adjacent wall when the door isclosed, the margins of said inner face of the door pressing against theouter sides of the margins of said strip all the way around, causingsaid strip to move inwardly all the way around when the door is inclosed position.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
